An EKG test is typically administered when there is cause for concern. Those in a normal state of health do not have a yearly EKG, for example. This test is administered when a person complains of chest pains or other problems where an issue with the heart may be indicated, according to MedlinePlus. When a doctor performs the test, individuals lie flat on the backs, and electrodes are attached to their arms, legs, and chests. These electrodes are hooked up to the EKG machine, which gives the doctor a printout. From this printout, the doctor can determine if heart problems are present. An EKG measures the size of the heart chambers, how fast the heart is beating and any current or past damage to the heart.Learn more about Diagnostics & Imaging
